Answer: [tex]\text{Area of the square shaped traffic sign }=16x^2+9+24x[/tex]
Step-by-step explanation:
Given: The side of the square shaped traffic sign = 4x+3
We know that the area of square is given by:-
[tex]Area= side^2[/tex]
Therefore, the area of the side of the square shaped field is given by:-
[tex]Area=(4x+3)^2[/tex]
We know that , [tex](a+b)^2=a^2+b^2+2ab[/tex]
Therefore,
[tex](4x+3)^2=(4x)^2+(3)^2+2(4x)(3)\\=16x^2+9+24x[/tex]
Hence, [tex]\text{Area of the square shaped traffic sign }=16x^2+9+24x[/tex]
